Abstract

The utility model discloses a globe valve for stamping, forging and welding, comprising a valve body, a valve cover, a valve clack, a valve rod and a hand wheel. The globe valve for stamping, forging and welding is characterized in that the valve body is composed of a medium diameter tube, two through diameter tubes, a base board, a middle flange and two connecting flanges. The left and right lateral walls of the medium diameter tube respectively have a circumferential notch at the top and at the bottom. One port of two through diameter tubes respectively is welded at the edge of two circumferential notches, and the other port of two through diameter tubes are respectively connected with the connecting flanges. A valve seat is welded between two circumferential notches at the top and bottom of the inner part of the medium diameter tube, the base board is welded at the lower port of the medium diameter tube and reinforcing ribs are welded in parallel between the medium diameter tube and two through diameter tubes. The globe valve for stamping, forging and welding can be made of hot (cold) stainless steel tubes and plates with high quality. The utility model which can be used for industry pipelines has advantages of low impurity content and light weight.

Description

Globe valve for stamping, forging and welding

The utility model relates to a kind of valve, particularly relates to a kind of impact forging weldering stop valve.

The stop valve of present industrial use, its valve body is a casting, and impurity, defective and seepage phenomenon are arranged in the foundry goods, its inner chamber turbidity test generally all are difficult to reach national C grade standard, and the stop valve volume of casting is big, heavy, waste material.

The purpose of this utility model is, for overcoming the deficiency of prior art, provides a kind of appearance neat and artistic to society, and its inner chamber turbidity test are better than national A grade standard, and volume is little, in light weight, the novel cutoff valve of saving material.

The utility model can be realized with following mode:

By valve body, valve gap, flap, valve rod, the impact forging weldering stop valve that handwheel is formed, its valve body is managed by middle footpath, two path tubes, base plate, middle flange and two adpting flanges are formed, on the left and right sides sidewall of middle footpath pipe, a garden v notch v is respectively arranged one on the other, one end of two parallel path tubes is that the shape of a saddle is welded in v notch v edge, two gardens respectively, the other end welds mutually with two adpting flanges respectively, two adpting flanges are parallel in Vertical direction, the footpath pipe was interior up and down between the two garden v notch vs during valve seat was welded in, the lower end was managed in the footpath during base plate was welded in, pipe upper end in footpath during middle flange is welded in, stiffening rib is parallel be welded between footpath pipe and two path tubes.

Two path tubes become 24-34 ° of angle with horizontal line.

Advantage of the present utility model:

1, appearance is clean and tidy, and inner cavity size is even, and the convection cell resistance is little, and the inner chamber turbidity test have surpassed the A level regulation of NBS JB/TQ407-85, and the inner chamber impurity content goes to zero;

2, valve body processing is simple, equipment needed thereby is few, investment is little;

3, valve body, valve gap can adopt the leftover pieces of high-quality heat (cold) steel rolling pipe and steel plate to manufacture, and the thin body of wall is light, can be country and save a large amount of steel, alleviate working strength of workers in the production, and alleviate the load of pipeline, transportation, loading and unloading, easy for installation;

4, raw material wide material sources, product cost is low, has good economic benefits and social benefit.

Fig. 1 is the utility model overall structure sectional view;

Fig. 2 is the valve body sectional view;

Below in conjunction with accompanying drawing the utility model is described further:

As shown in drawings, by middle footpath pipe 7, path tube 8,13, base plate 12, middle flange 6, adpting flange 9,14 form valve body, in the footpath manage 7 the left and right sides sidewall garden v notch v respectively arranged one on the other, path tube 8, an end of 13 is that the shape of a saddle is welded in v notch v edge, two gardens respectively, the other end respectively with adpting flange 9,14 welding mutually, path tube 8 becomes 24-34 ° of angle to be parallel to each other with 13 with horizontal line, be that 34 ° of adpting flanges 9 and 14 are parallel to each other in Vertical direction in the present embodiment, managed in 7 up and down between the two garden v notch vs in the footpath during valve seat 11 was welded in, 7 lower ends were managed in the footpath during base plate 12 was welded in, the footpath manages 7 and path tube 8 in two stiffening ribs, 17 parallel being welded in, between 13, angle between two stiffening ribs 17 and the horizontal line is between 24-34 °, present embodiment is 34 °, 7 upper end-hole were managed in the footpath during middle flange 6 was welded in, valve gap 5 is linked to each other with middle flange 6 by bolt, pressing plate 16 links to each other with follower 15, valve rod 3 lower ends link to each other with flap 10, valve rod positioning block 2 is linked to each other with valve gap 5 by column 4, valve rod 3 tops are equipped with handwheel 1, state shown in Figure 1 is that stop valve is closed schematic representation, rotation hand wheel 1, valve rod 3 rises, stop valve is promptly opened, and the leftover pieces that valve body adopts high-quality heat (cold) to roll Stainless Steel Tube and steel plate are made.
